Bankside is delighted to welcome senior advocate Brent O’Callahan to chambers. With more than 30 years' experience in commercial and civil litigation, Brent has acted in hundreds of cases before New Zealand’s senior courts, frequently involving complex disputes in company law, insolvency, asset recovery, equitable claims, and interim relief such as freezing and charging orders.
Brent was admitted as a barrister and solicitor of the High Court of New Zealand in 1995. He began his career at Carter & Partners, where he became a partner in 2002, and later joined Auckland-based firm K3 Legal as a partner. In 2019, he joined Arapata Chambers as a barrister sole.
Recognised for his sharp analytical skills and strategic insight, Brent represents private individuals, insolvency practitioners, and corporate clients in high-stakes litigation, with particular expertise in multi-party disputes, cross-border enforcement, and urgent interlocutory applications.
“Brent is well regarded for his strategic insight, persuasive advocacy, and commitment to justice,” says Bankside Board Chair Philip Skelton KC. “We are pleased to have Brent O’Callahan join our set.”
Brent is perhaps best known for his work acting for Michael Kidd in his successful long running and multi-jurisdictional claim against Alex van Heeren to recover his share of an international partnership – thought to be the most complex civil case ever to come before the New Zealand Courts.
